Starting from ArubaOS 188.8.131.52, the "wipe out flash" command is introduced. This command erases all data including configuration, logs, license keys, flash backup files and formats the flash file system in the controller.
This command can be executed from any mode(privilege/ configuration) of the the controller
(Aruba-Controller) #wipe out flash
Once this command is executed we will get the following caution message
"Flash filesystem will be formatted.
Configuration, databases and all the files will be deleted. Press 'y' to proceed :"
Proceed either by typing "y" to proceed with the format or "n" to cancel the flash wipe out.
